Can lenticular posters be signed with a permanent marker or Sharpie?

Writing directly on the textured lenticular lens with a permanent marker or Sharpie is generally not recommended. The ridged lens surface keeps ink from sitting smoothly, so it can smear or fail to adhere evenly.

• Permanent marker may smear or bead rather than dry cleanly, and standard pens fare no better, since ink catches on the ridges.
• If you need a signable area, design a smooth, non-lenticular space into the layout and plan it before you order.
• Use a permanent marker on that area and let the ink dry before handling.
• Ask your printer about the best autograph area and a compatible marker before ordering signed memorabilia for events or meet-and-greets.
